Diener Precision Pumps (DPP) is a leading designer and manufacturer of custom precision gear and metering pumps for medical, laboratory, printing, cooling, food handling and many other crucial industries.
Diener Precision Pumps provides engineered pumps for medium and high volume OEM customers in the high-tech fluids markets. Our pumps are customized to give customers exactly what they need. This reduces engineering costs, procurement costs, and shortens installation times for a lower “installed” cost.
Our products are manufactured to very tight tolerances to ensure consistent pump-to-pump performance. They are quiet, durable, and very compact. Sophisticated drive electronics allows quick pump responses to changing flow and pressure requirements. Each pump is 100% tested and laser-marked to ensure we’ve met customer requirements and guarantee traceability.
Whether you need micro-dosing/metering or the continuous high pressure pulseless flows of our gear pumps, Diener has the product range to meet your requirements. The pumps below are the basis for medium and large OEM production variants. All pumps are customized to suit customer requirements.
Innovative design allows precise mixing, simultaneous dosing or out-of-phase delivery.
The Extreme Series gear pump is designed for high stress loads. It can easily pump difficult fluids from pigmented inks to strawberry smoothies.
The Optima Series gear pumps are your first choice in any application in which a constant delivery volume is required at high pressure in a compact area.
The highest precision metering pump for sensitive applications in analytical, diagnostic and medical technologies.
Silencer LD extends the successful Silencer series gear pump to light duty applications requiring a more compact size.
The Silencer Series gear pumps were designed from scratch to be everything a gear pump should be: durable, leak-free, reliable, chemically inert and quiet.
Follow the steps below and help us develop a pump that delivers the performance you need.
We start with a full definition of your requirements beginning with your specifications.
Our engineering team will review your requirements and start the dialog to clarify performance requirements. We contact your team, share technical information and CAD models, and establish project goals and timelines.
Diener have a dedicated prototype shop where we can create or modify designs to fit your needs. We understand the need to stay on schedule, so our goal is to provide prototype sample pumps within days of receiving your inquiry.
The validation/verification step ensures we’ve met your requirements. A complete review of manufacturing processes ensures that we can consistently provide the highest quality product within your budget limits.
Discover our portfolio of precise, high-performance and robust dosing pumps and gear pumps for your individual area of application.
Diagnostic and Medical equipment covers a wide range of products and Diener Precision Pumps are ideal for all of them. Our gear pumps are typically used for waste and bulk fluid transfer applications, whereas our metering/dosing pumps are used where ultra-low (micro-dosing) is required.
Diener Precision gear pumps are the ideal choice for cooling systems, whether they be water, water/glycol, di-electric, or freon-based.
Diener pumps are the go-to solution for sterilization systems, whether they be for surgical equipment cleaning or disinfection spray systems to combat the spread of the Covid-19 virus.
Pulse-free pressure delivery, able to pump all types of dye and solvent-based inks, magnetically-coupled drives, precision performance electronic control; these are the features that make Diener Precision Pumps the preferred choice in continuous inkjet printers.
Diener Precision Pumps complete line of “flow-thru” design pumps are ideal for beverage transfer and dispensing. This feature allows very quick clean-in-place flexibility and is certified to the National Sanitary Foundation (NSF/ANSI 169).
Repeatable pump-to-pump performance and micro-dosing is achieved via extremely small manufacturing tolerances, making for a better dialysis treatment and an enhanced patient experience.
At DPP, quality is more than just a word, quality is our conviction, our philosophy and what we achieve every day. From product development in Lodi, California, to production in Embrach, Switzerland and to providing support to our customers, there is only one standard we live by, to offer the very best.
We perform all prototype design/construction from our California R&D facility. Prototype design/fabrication range from 2-15 days. Prices vary depending on complexity.
Custom is sometimes misinterpreted to mean expensive. This is not the case. Designing a pump for a specific application ensures optimum performance, a small package size, minimum power consumption and long life—resulting in space savings, low power consumption and a lower installed cost.
DPP designs and manufactures custom pumps to fulfill your OEM equipment requirements.
DPP tests at your operating conditions. This ensures that the pump performs to expectation before you validate in your equipment. We are also capable of conducting long-term endurance testing, environmental and chemical compatibility testing.
No. Every pump is designed and tailored to our customer’s exact needs. We have a minimum volume requirement of 100 pieces/year.
The customer provides DPP with the performance requirements via an Application Data Sheet (ADS). DPP uses this information to size the pump, design the interfaces and set up the test/validation program.
External gear pumps are a type of rotary positive displacement pump tracing back to the late sixteenth century. They were often driven by water wheels as they can utilize simple rotation of gears to transfer fluids.
